Description
Technical field
The present invention relates to water-treatment technology field, relate to a kind of degradable material for pollutent particularly, particularly a kind of matrix material of fast deep process Organochlorine Pesticide Wastewater, and the Synthesis and applications of described matrix material.
Technical background
Organochlorine pesticide is mainly divided into benzene to be raw material and to take cyclopentadiene as two large classes of raw material.With benzene be the organochlorine pesticide of raw material comprise use the earliest, most widely used sterilant DDT, phenyl-hexachloride, lindane, methoxy DDT, Perthane, also comprise some sterilant, as quintozene, m-tetrachlorophthalodinitrile, Rabcon etc., and broad-spectrum herbicide Diuron Tech, chlorotoluron etc.Take cyclopentadiene as the Niran, heptachlor, 5a,6,9,9a-hexahydro-6,9-methano-2,4, Dieldrin-attapulgite mixture, aldrin, endrin, carbon chlorine Trane etc. that the organochlorine pesticide of raw material comprises as sterilant.In addition be the amphene insecticides of raw material with turps, toxaphene and be that the bornyl chloride of raw material also belongs to organochlorine pesticide with terpenes.Organic chlorine agriculture chemicals is that in agricultural chemicals history, usage quantity is maximum, uses the class agricultural chemicals that history is the longest, its stable chemical nature, by force fat-soluble, in the longevity of residure long (can for 30 ~ 50 years), easily accumulate in fatty tissue, cause chronic poisoning, seriously jeopardize HUMAN HEALTH.Therefore efficient organochlorine pesticide treatment technology must be adopted to carry out degradation treatment to it, to reduce the malicious influences to the ecosystem.
Tradition water treatment method mainly utilizes additional reaction reagent (as Cl
2, ClO
2, H
2o
2, O
3) etc. produce effective active species (as free radical etc.) and eliminate with pollutant reaction, or by sorbent material (flocculation agent, gac etc.) or filtering membrane etc., separated from contaminants is shifted, seldom there is selectivity, one contact scar thing of rather high concentration can be eliminated by efficient and cost-effective, but both lacked validity to the elimination of lower concentration, high toxicity, Recalcitrant chemicals (as halo organic pesticide) and also lacked economy, conventional biochemical processing method is substantially invalid to this compounds.Domestic and international association area researchist has expanded a large amount of research work, has inquired into multiple degraded or process Organohalogen compounds approach, wherein zero-valent metal particularly Zero-valent Iron receive the concern of people gradually as a kind of reductive agent of effective dehalogenation.Zeroth order Nanoscale Iron has large, the active high feature of specific surface area, but Nanoscale Iron has easy reunion, oxidizable feature.Therefore adopt suitable modification and load means effectively can alleviate Nanoscale Iron and there is easy reunion, oxidizable problem.In addition due to the difference of different organochlorine pesticide bulks of molecule and polarity, the carrier designing different characteristics is needed to go to reach the effect removed Organochlorine Pesticides.
Summary of the invention
For solving the problems of the technologies described above, the invention provides a kind of matrix material of fast deep process Organochlorine Pesticide Wastewater, it is characterized in that, described matrix material comprises Nanoscale Iron and carrier, and the weight part of the two is respectively 5-20 weight part and 80-95 weight part; Described carrier is active carbon fiber felt or active carbon fiber fabrics and the mixture deriving from biological carbon based material, and the weight ratio of the two is 9:1-1:9; The diameter of described Nanoscale Iron is about 100nm.
Deriving from biological carbon based material is the carbon based material deriving from animal excrement, animal bone, plant roots and stems, wood chip, bamboo charcoal, Wheat Straw, coconut husk, Pericarppium arachidis hypogaeae.The described carbon based material deriving from biology has different pore diameter characteristics and adsorpting characteristic, all has good treatment effect to the Organochlorine Pesticides of different characteristics.
Preferably, the weight part of Nanoscale Iron and carrier is respectively 8-15 weight part and 85-92 weight part; More preferably, the weight part of Nanoscale Iron and carrier is respectively 10-14 weight part and 86-90 weight part; Most preferably, the weight part of Nanoscale Iron and carrier is respectively 12 weight parts and 88 weight parts.
Preferably, described active carbon fiber felt or active carbon fiber fabrics are 1:1 with the weight ratio of the carbon based material deriving from biology.
Further, the preparation method of above-mentioned matrix material is provided, it is characterized in that: adopt liquid phase reduction, according to corresponding ratio, described Nanoscale Iron is loaded on carrier, dries subsequently; The activated carbon fiber of final loaded with nano-iron derives from biological carbon based material with the wrapped loaded with nano-iron of felt or cloth.
Further, the present invention also provides the application above-mentioned matrix material being used for fast deep process Organochlorine Pesticide Wastewater, it is characterized in that: the material for core above-mentioned matrix material being used as water treatment filter.
Described material for core is that the activated carbon fiber of loaded with nano-iron derives from biological carbon based material with the wrapped of felt or cloth; Or the material for core of carbon based material particle as water treatment filter deriving from biology of the activated carbon fiber fragment of loaded with nano-iron and loaded with nano-iron.
Especially, matrix material of the present invention is for the application of the agricultural chemicals waste water of fast deep process Diuron Tech, monuron.Described agricultural chemicals waste water is the waste water produced in pesticide producing.
The present invention adopts active carbon fiber felt, active carbon fiber fabrics and derives from biological carbon based material as carrier, what it utilized is that the feature (namely conveniently making the form such as felt, cloth) of the easy through engineering approaches of activated carbon fiber and different sources charcoal sill have different pore size distribution characteristics, realizes the efficient degradation to organochlorine pesticide class.The weight part of above-mentioned Nanoscale Iron and carrier, is guarantee that the duct between active carbon fibre peacekeeping carbon based material is unimpeded simultaneously.
Beneficial effect of the present invention is as follows:
(1) adopt activated carbon fiber with the wrapped different sources charcoal sill of felt or cloth, there is the feature of easy through engineering approaches, easy to use and regeneration;
(2) different sources charcoal has different pore diameter characteristics and surface group distribution, and then widens the kind that can process organochlorine pesticide;
(3) load of Nanoscale Iron can improve the feature eliminating organochlorine pesticide greatly, because degraded efficiently while adsorption and enrichment, avoids the saturation effect of adsorbing merely and having;
(4) charcoal derives from animal excrement, animal bone, plant roots and stems, wood chip, bamboo charcoal, Wheat Straw, coconut husk, Pericarppium arachidis hypogaeae the like waste, has utilization of waste material, energy-saving and emission-reduction, feature that cost is low;
(5) adopt matrix material of the present invention can realize the degraded of organochlorine pesticide fast, within 30 minutes, degraded is complete substantially.
Accompanying drawing illustrates:
Fig. 1: matrix material of the present invention is to the degradation property curve of organochlorine pesticide Diuron Tech.
